Detailed implementation manners

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Referring to Figures 1-4 , a drawing frame, including a main board 1, a chute 101 is provided on the surface of the main board 1, a plurality of card slots 102 are provided on the inner wall of the chute 101, and a plurality of separating components 2 are inserted into the inner cavity of the card slots 102. The separating components 2 are used for separating cotton strips. A forming component 3 is installed on the surface of the main board 1, and the forming component 3 is used for drawing the cotton strips. It further includes:

[0024] The separating component 2 includes an insertion block 201, the insertion block 201 is inserted into the inner cavity of the card slot 102, and the insertion block 201 can extend through the main board 1 to the bottom. A connecting block 202 is fixedly connected to the top of the insertion block 201, and the connecting block 202 is located in the inner cavity of the chute 101. A ring sleeve 203 is fixedly connected to the top of the connecting block 202. A fixing bolt 204 is threadedly connected to the bottom of the main board 1, and the fixing bolt 204 can penetrate through the insertion block 201;

[0025] It should be noted that: since a plurality of groups of card slots 102 are provided on the inner wall of the chute 101, the insertion block 201 can be inserted into the inner cavity of the card slot 102 according to the number of cotton strips and the required spacing. After the insertion is completed, rotate the fixing bolt 204 at the bottom of the main board 1 to make the fixing bolt 204 penetrate through the insertion block 201, so as to fix the ring sleeve 203 on the surface of the main board 1. Subsequently, the cotton strips can pass through a plurality of ring sleeves 203, and finally the forming component 3 is used for drawing.

[0026] Referring to Figures 1-4 , a sliding column 205 is slidably connected to the top of the ring sleeve 203. A spring 206 is fixedly connected between the top of the sliding column 205 and the ring sleeve 203. A pressing plate 207 is fixedly connected to the bottom end of the sliding column 205 located inside the ring sleeve 203;

[0027] An installation frame 208 is clamped on the surface of the main board 1 above the ring sleeve 203. A threaded column 209 is threadedly connected to the top of the installation frame 208. The bottom of the threaded column 209 is rotatably connected to a fixing plate 210;

[0028] It should be noted that: by virtue of the elastic force of the spring 206, the sliding column 205 and the pressing plate 207 are located above the sleeve 203, which does not affect the placement of the sliver. And since the mounting frame 208 is detachably arranged with the main board 1, it does not affect the adjustment of the sleeve 203. After placing the sliver in the inner cavity of the sleeve 203, the mounting frame 208 is snap-fitted on the surface of the main board 1. Subsequently, the threaded column 209 is rotated. The threaded column 209 drives the fixing plate 210 to slide downward. The fixing plate 210 will squeeze the sliding column 205 to slide downward. The sliding column 205 drives the pressing plate 207 to press downward, so as to position the sliver at the bottom of the inner cavity of the sleeve 203, avoiding the sliver from shaking during the transmission in the inner cavity of the sleeve 203 and causing uneven drawing.

[0029] Referring to Figures 1-4 , the forming component 3 includes a bidirectional threaded rod 301. The bidirectional threaded rod 301 is rotatably installed on the inner wall of the main board 1. Both side walls of the bidirectional threaded rod 301 are threadedly connected with sliding blocks 302;

[0030] The top of the sliding block 302 is fixedly connected with a motor 303. The output end of the motor 303 is fixedly connected with a rotating shaft. The top end of the rotating shaft is fixedly connected with a pressing wheel 304;

[0031] The bottom of the pressing plate 207 is arc-shaped. A nut 305 is threadedly connected to the side wall of the bidirectional threaded rod 301 on the outer side of the main board 1;

[0032] It should be noted that: when the bidirectional threaded rod 301 is rotated, since both side walls of the bidirectional threaded rod 301 are threadedly connected with the sliding blocks 302, when the bidirectional threaded rod 301 rotates, the sliding blocks 302 will move away from or close to each other on the side walls of the bidirectional threaded rod 301 at the same time. Since the pressing wheel 304 is used to clamp the sliver in the middle position and the driving motor 303 is driven, the motor 303 drives the rotating shaft to rotate, and the rotating shaft drives the pressing wheel 304 to rotate, so as to clamp and draw the sliver. And after the position of the pressing wheel 304 is adjusted by using the bidirectional threaded rod 301, the nut 305 can be rotated to fix the bidirectional threaded rod 301. The pressing plate 207 is arc-shaped to facilitate squeezing the sliver in the inner cavity of the sleeve 203.

[0033] Operation mode: Since the mounting frame 208 and the main board 1 are detachably arranged, it does not affect the adjustment collar 203. Multiple groups of clamping grooves 102 are provided on the inner wall of the sliding groove 101. Therefore, according to the number of cotton strips and the required spacing, the insertion block 201 can be inserted into the inner cavity of the clamping groove 102. After the insertion is completed, rotate the fixing bolt 204 at the bottom of the main board 1 so that the fixing bolt 204 penetrates through the insertion block 201, thereby fixing the collar 203 on the surface of the main board 1. Due to the elastic force of the spring 206, the sliding column 205 and the pressing plate 207 are located above the collar 203, which does not affect the placement of the cotton strip. After placing the cotton strip in the inner cavity of the collar 203, snap the mounting frame 208 onto the surface of the main board 1, and then rotate the threaded column 209. The threaded column 209 drives the fixing plate 210 to slide down. The fixing plate 210 will squeeze the sliding column 205 to slide down, and the sliding column 205 drives the pressing plate 207 to press down, thereby positioning the cotton strip at the bottom of the inner cavity of the collar 203 and preventing the cotton strip from shaking during transmission in the inner cavity of the collar 203, resulting in uneven drawing;

[0034] Rotate the bidirectional threaded rod 301. Since sliding blocks 302 are threadedly connected to both side walls of the bidirectional threaded rod 301, when the bidirectional threaded rod 301 rotates, the sliding blocks 302 will move away from or close to each other on the side wall of the bidirectional threaded rod 301 at the same time. Since the cotton strip is clamped in the middle position by the pressing wheels 304, and the driving motor 303 drives the rotating shaft to rotate, and the rotating shaft drives the pressing wheels 304 to rotate, thereby clamping and drawing the cotton strip. And after adjusting the position of the pressing wheels 304 by using the bidirectional threaded rod 301, the bidirectional threaded rod 301 can be fixed by rotating the nut 305.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
